Title: PHOTOPLETHYSMOGRAPHIC WEARABLE BLOOD PRESSURE MONITORING SYSTEM AND METHODS
Abstract:
A method for estimating blood pressure, including : identifying representative PPG pulse curve shapes associated with first and second direct non-invasive blood pressure measurements; generating at least one blood pressure correlation function representing at least a relationship between a first difference between the first shape and the second shape and a second difference between the first direct blood pressure measurement and the second direct blood pressure measurement; obtaining a measured PPG pulse signal from a patient; identifying a measured representative shape of a measured PPG pulse curve from the measured PPG pulse signal; and generating an estimated blood pressure based on the measured representative shape and the at least one blood pressure correlation function.
